Although we live in an age dominated by science and technology, there exists an increasingly popular anti-science sentiment. This study describes the development of a scale to assess the degree of personal acceptance of supernatural causality versus acceptance of scientific explanation. In addition to the psychometric data concerning validity and reliability of the scale, data are presented which showed the personality factor of supernaturalism to be independent of orthodox religious attitudes. Results indicated a significantly greater supernatural acceptance for women, and a positive relation of supernaturalism with external locus of control. 相似文献

A profoundly retarded 28-yr.-old female was trained to avoid an aversive but harmless shock to the foot by withdrawing the foot upon presentation of a visual cue. She was later unable to learn to avoid the shock consistently upon presentation of an auditory cue, confirming the ward staff's contention that she had a hearing disability. The audiometric technique using negative reinforcement bridges the problems of (1) difficulty in finding positive reinforcers for patients of low functioning and (2) satiation which may result from the continued use of positive reinforcers. The use of aversive stimuli raises ethical concerns. The growing trend in research is that aversive stimuli are permissible for individuals for whom positive techniques have not been effective and when used by trained professionals under careful review. 相似文献

Working memory (WM) span tasks—and in particular, counting span, operation span, and reading span tasks—are widely used measures
of WM capacity. Despite their popularity, however, there has never been a comprehensive analysis of the merits of WM span
tasks as measurement tools. Here, we review the genesis of these tasks and discuss how and why they came to be so influential.
In so doing, we address the reliability and validity of the tasks, and we consider more technical aspects of the tasks, such
as optimal administration and scoring procedures. Finally, we discuss statistical and methodological techniques that have
commonly been used in conjunction with WM span tasks, such as latent variable analysis and extreme-groups designs. 相似文献

Transitive inference (TI) in animals (e.g., choosing A over C on the basis of knowing that A is better than B and B is better than C) has been interpreted by some as reflecting a declarative logical inference process. We invert this anthropomorphic interpretation by providing evidence that humans can exhibit TI-like behavior on the basis of simpler associative mechanisms that underlie many theories of animal learning. In this study, human participants were trained on a five-pair TI problem (A+B-, B+C-, C+D-, D+E-, E+F-) and, unlike in previous human TI studies, were prevented from becoming explicitly aware of the logical hierarchy, so they could not employ logical reasoning. They were then tested with three problems: B versus D, B versus E, and C versus E. Participants only reliably chose B over E, whereas the other test conditions yielded chance performance. This result is inconsistent with the use of logical reasoning and is instead consistent with an account developed to explain earlier TI studies with rats that found the same pattern of results. In this account, choice performance is based on differential associative strengths across the stimulus items that develop over training, despite equal overt reinforcement. 相似文献

High and low working memory (WM) capacity individuals performed the serial reaction time task under both incidental and intentional learning conditions to determine the role of WM capacity in the learning of sequential information. WM capacity differences emerged in conditions of intentional but not incidental learning, indicating that individual differences in WM capacity occur in tasks requiring some form of control, with little difference appearing on tasks that required relatively automatic processing. Furthermore, an index of learning was significantly related to a measure of general fluid intelligence under intentional conditions only. Thus, the degree of learning was significantly related to higher order cognition, but only when intentional processing was emphasized. 相似文献

The present investigation provides a longitudinal study of an individual (RB) with acquired alexia following left posterior cerebral artery stroke. At initial testing, RB exhibited acquired alexia characterized by letter-by-letter (LBL) reading, mild anomic aphasia, and acquired agraphia. Repeated measures of reading accuracy and rate were collected for single words and text over the course of one year, along with probes of naming and spelling abilities. Improvements associated with natural recovery (i.e., without treatment) were documented up to the fourth month post onset, when text reading appeared to be relatively stable. Multiple oral reading (MOR) treatment was initiated at 22 weeks post-stroke, and additional improvements in reading rate and accuracy for text were documented that were greater than those expected on the basis of spontaneous recovery alone. Over the course of one year, reading reaction times for single words improved, and the word-length effect that is the hallmark of LBL reading diminished. RB's response to treatment supports the therapeutic value of MOR treatment to in LBL readers. His residual impairment of reading and spelling one-year post stroke raised the question as to whether further progress was impeded by degraded orthographic knowledge. 相似文献

The authors argue that a robust version of Cohen's effect size constructed by replacing population means with 20% trimmed means and the population standard deviation with the square root of a 20% Winsorized variance is a better measure of population separation than is Cohen's effect size. The authors investigated coverage probability for confidence intervals for the new effect size measure. The confidence intervals were constructed by using the noncentral t distribution and the percentile bootstrap. Over the range of distributions and effect sizes investigated in the study, coverage probability was better for the percentile bootstrap confidence interval. 相似文献

Taking the possibility of visual argumentation seriously, this essay explores how refutation might proceed. We posit three ways in which images can refute and be refuted in a mixed-media environment: (1) dissection, in which an image is broken down discursively; (2) substitution, in which one image is replaced within a larger visual frame by a different image; and (3) transformation, in which an image is recontextualized in a new visual frame. These strategies are illustrated in an analysis of three American documentary films on abortion. 相似文献
